#Rediswalker

##Overview:

##What the structure should look like:

	redisKey: { 
		 obj1: unix_epoch_timestamp,
		 obj2: unix_epoch_timestamp,
		 ...
		 objn: unix_epoch_timestamp
	}

The redisKey in this key should be associated with a redis sorted set.

##How to use it:

1. Create a new instance of this walker with the appropriate params

var walker = new Walker(couchUrl, sortedSetKey); 

1. Daemonize the process, so it runs forever in the background
2. Done!
